Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0049] Referring to Figure 1 , an embodiment of the present invention provides a method for handling communication faults of an automotive sunroof, and this method is applied to a sunroof controller. During the application process, this method includes but is not limited to the following steps:

[0050] Step S110: Determine that a communication fault occurs in the local area network subsystem of the automotive sunroof, and obtain the state of the first sunroof glass;

[0051] Step S120: When it is determined that the sunroof glass is fully closed according to the state of the first sunroof glass, obtain the long-press signal of the sunroof glass opening button as the first signal;

[0052] Step S130: Obtain the state of the first sunroof sunshade and the state of the second sunroof glass according to the first signal;

[0053] Step S140: Analyze the fault type of the local area network subsystem according to the state of the first sunroof sunshade and the state of the second sunroof glass, where the fault type includes an external local area network subsystem fault and an internal local area network subsystem fault.

[0054] In the embodiment of the present application, a target fault execution program can be preset in the sunroof controller, and the states of the sunroof and the sunshade corresponding to different fault types are set in this program. Specifically, when analyzing the fault type of the local area network subsystem according to the state of the first sunroof sunshade and the state of the second sunroof glass, in combination with the preset state correspondence relationship, the judgment process can be executed through the following steps:

[0055] When the state of the first sunroof sunshade is fully closed and the state of the second sunroof glass is fully closed, it is determined that both the external local area network subsystem and the internal local area network subsystem have failed;

[0056] When the first sunroof sunshade is in the semi-closed state and the second sunroof glass is in the semi-closed state, it is determined that the external local area network subsystem has a fault and the internal local area network subsystem is normal;

[0057] When the first sunroof sunshade is in the fully closed state and the second sunroof glass is in the semi-closed state, it is determined that the external local area network subsystem is normal and the internal local area network subsystem has a fault.

[0058] It can be understood that, in combination with the judgment process of this embodiment, the corresponding fault types can be represented by Table 1:

[0059] Table 1

[0060]

[0061] For the corresponding fault types in Table 1, when it is found during the detection process that as Figure 2 shown, when both the sunroof sunshade 220 and the sunroof glass 210 are in the fully closed state, it can be determined that both local area network subsystems (Local Interconnect Network, LIN) are in a fault state. When it is found during the detection process that as Figure 3 shown, when both the sunroof sunshade 220 and the sunroof glass 210 are in the semi-closed state, it can be determined that the external local area network subsystem in the LIN has a fault but the internal local area network subsystem is normal. When it is found during the detection process that as Figure 4 shown, when the sunroof sunshade 220 is in the fully closed state and the sunroof glass 210 is in the semi-closed state, it can be determined that the external local area network subsystem in the LIN is in a normal state but the internal local area network subsystem is in a fault state.

[0062] In the embodiment of the present application, when it is determined that there is a communication fault in the local area network subsystem of the vehicle sunroof, the control indicator light executes the first display state; when it is determined according to the state of the first sunroof glass that the sunroof glass is not fully closed, the control indicator light executes the second display state, and a jog-close signal for the sunroof glass is obtained; wherein, the jog-close signal for the sunroof glass is used to indicate closing the sunroof glass. Specifically, the sunroof controller in this embodiment includes a glass controller and a sunshade controller. Specifically, as Figure 5As shown, the glass controller is provided with a communication failure standby action interface, a LIN communication failure signal output terminal, and a communication failure warning light terminal. Moreover, the glass controller is connected to the body control module through an external local area network subsystem, and the glass controller is connected to the sunshade controller through an internal local area network subsystem. The indicator light is connected to the communication failure warning light terminal of the glass controller. In this embodiment, when the glass controller internally detects an external LIN or internal LIN communication failure, through an internal program, the glass controller and the sunshade controller will be determined to be in the "communication failure mode". At this time, a high-level signal is output at the "LIN communication failure signal output" interface, the collector and emitter of the triode are turned on, the relay is attracted, and at the same time, a high-level signal is given to the "communication failure standby action interface of the glass controller", and the "communication failure standby action mode" is started inside the glass controller. At the same time, a high-level signal is output at the "communication failure warning light output", and the light-emitting diode is turned on to emit light to remind the user that the sunroof is in the communication failure mode.

[0063] When entering the "communication failure standby action" mode, as Figure 6 shown, first, it is detected whether the sunroof glass is in the fully closed state. If the glass is not fully closed, the fault warning light flashes to remind the user that there is a communication failure in the sunroof system, and the sunroof is closed by operating the sunroof glass closing button; if the sunroof glass is fully closed, the fault warning light is on constantly to remind the user that there is a communication failure in the sunroof system and do not open it again. Next, the sunroof system will start the "communication failure detection" mode.

[0064] When entering the "communication failure detection" mode, as Figure 6 shown, first, it is necessary to long-press the sunroof glass opening button. At this time, the system detects the long-press action of the glass opening button. The sunroof system controller will judge whether the external LIN communication is faulty. If the external LIN communication is normal, the system internally determines it as fault mode C in Table 1. At this time, the sunroof performs Figure 4 the actions shown, the sunroof glass opens to the halfway position, the sunshade does not open, and the warning light flashes. If the external LIN communication is faulty, the system then judges whether the internal LIN communication is faulty. If the internal LIN communication is normal, the system internally determines it as fault mode B in Table 1. At this time, the sunroof performs Figure 3 the actions shown, the glass opens fully, the sunshade opens fully, and the warning light flashes. If the internal LIN communication is faulty, the system internally determines it as fault mode A in Table 1. At this time, the sunroof performs Figure 2 the actions shown, neither the sunroof glass nor the sunshade opens, and the warning light is on constantly.

[0065] In the embodiment of the present application, for different fault types, corresponding fault types can be displayed by setting multiple light-emitting diodes. Specifically, as Figure 7As shown in the figure, multiple light-emitting diodes include a first diode D1, a second diode D2, and a third diode D3. The anodes of the first diode D1, the second diode D2, and the third diode D3 are all connected to the output terminal of the glass controller, and the cathodes of the first diode D1, the second diode D2, and the third diode D3 are grounded through a resistor R. In this embodiment, by setting multiple light-emitting diodes corresponding to different fault types, the effect of classifying and judging the skylight communication fault is achieved, and the process of judging the classification by saving the skylight operation situation and the warning light situation is saved.

[0066] In summary, the embodiment of the present application provides a skylight communication fault reminder function for users. When a communication fault occurs, the skylight glass can take an emergency closing measure to avoid the risk of vehicle damage caused by external foreign objects, rain, and dust entering the vehicle in the case of a communication fault. And by controlling the internal program to add a communication fault self-check mode, maintenance personnel can, without using an OBD detection tool to read the fault code, achieve the effect of detecting the communication fault through the skylight actuation action and the warning light flashing situation, thereby improving the skylight fault detection and maintenance efficiency.
